If co-operation, is thus the lifeblood of science and technology, it is similarly vital to society as a whole.

Twenty thousand years ago the family was the social unit. Now the social unit has become the world, in which it may truthfully be said that each person's welfare affects that of every other.

Yet is it possible in terms of the motion of atoms to explain how men can invent an electric motor, or design and build a great cathedral? If such achievements represent anything more than the requirements of physical law, it means that science must investigate the additional controlling factors, whatever they may be, in order that the world of nature may be adequately understood.

Typical of the fundamental scientific problems whose solution should lead to important industrial consequences are, for example, the release of atomic energy, which experiment has shown to exist in quantities millions of times greater than is liberated by combustion.

The benefits of science are not only material ones. The truths that science teaches are of common interest the world over. The language of science is universal, and is a powerful force in bringing the peoples of the world closer together.

To make the moral achievement implicit in science a source of strength to civilization, the scientist will have to have the cooperation also of the philosopher and the religious teacher.

Those whose thinking is disciplined by science, like all others, need a basis for the good life, for aspiration, for courage to do great deeds. They need a faith to live by. The hope of the world lies in those who have such faith and who use the methods of science to make their visions become real. Such visions and hope and faith are not a part of science.
